Recurrent Entity Networks

This repository contains an independent TensorFlow implementation of recurrent entity networks from Tracking the World State with Recurrent Entity Networks. This paper introduces the first method to solve all of the bAbI tasks using 10k training examples. The author's original Torch implementation is now available here.

NOTE: Some of these tasks (16 and 19, in particular) required a change in learning rate schedule to reliably converge.

Setup

1. Download the datasets by running download_babi.sh or from The bAbI Project.
2. Run prep_data.py which will convert the datasets into TFRecords.
3. Run python -m entity_networks.main to begin training on QA1.

Major Dependencies

• TensorFlow v1.1.0

Thanks!

• Thanks to Mikael Henaff for providing details about their paper over Thanksgiving break. :)
• Thanks to Andy Zhang (@zhangandyx) for helping me troubleshoot numerical instabilities.
• Thanks to Mike Young (@mikalyoung) for providing results on some of the longer tasks.
